With the help of a herd of Elephants living in Northern Thailand, this one-of-a-kind brew gets its earthy flavour from being digested by the elephants and then collected from their dung a day later. Apparently, it is a gut reaction within the elephant’s stomach that creates the unusual taste. At $500 per pound ($1100 per kilogram), this coffee is not only different, it is also the world’s priciest coffee ever made.
